摘要： In accordance with presently disclosed embodiments, systems and methods for selectively engaging, raising or lowering, and disengaging downhole equipment via a reduced friction J-latch mechanism is provided. The disclosed J-latch mechanism generally includes a J- latch receptacle including a cylinder having a slot formed therein, the slot having an open end exposed at one end of the cylinder and a truncated slot area at an opposite end of the slot from the open end. The J-latch mechanism also includes a J-latch lug member including a mounting portion with a lug disposed thereon for removably interfacing with the slot of the J-latch receptacle. The lug includes a bearing assembly to reduce friction between the slot and the lug while selectively engaging and disengaging the lug member from the receptacle. The disclosed J-latch mechanism may improve the efficiency of deployment, retrieval, and actuation of a wide range of oilfield equipment under heave conditions.
摘要翻译：根据目前公开的实施例，提供了用于通过减小的摩擦J型闩锁机构选择性地接合，升高或降低和分离井下设备的系统和方法。所公开的J型闩锁机构通常包括一个J型闩锁插座，其包括一个其中形成有槽的汽缸，该槽的开口端暴露在气缸的一端，并且在槽的相对端与开口结束。 J型闩锁机构还包括一个J形闩锁突起构件，其包括安装部分，该安装部分设置有用于可拆卸地与J型闩锁插槽的狭槽对接的耳片。凸耳包括一个轴承组件，用于减小槽和凸耳之间的摩擦，同时选择性地使凸耳件与容器接合和脱开。所公开的J型闩锁机构可以提高在起伏条件下广泛的油田设备的部署，检索和致动的效率。

摘要： A method of drilling and completing a well can include drilling a section of a wellbore, positioning a perforated shroud in the section of the wellbore, securing the perforated shroud by setting a hanger, and isolating the section of the wellbore from a remainder of the wellbore vertically above the section of the wellbore. The drilling, positioning, securing and isolating steps can be performed while the section of the wellbore is not exposed to a liquid column extending to a surface location. The drilling, positioning, securing and isolating steps can be performed in a single trip of a drill string into the wellbore.
摘要翻译：钻井和完井的方法可以包括钻井井的一部分，将穿孔护罩定位在井筒的部分中，通过设置悬挂器固定穿孔护罩，并将井筒的部分与井筒的其余部分隔离垂直于井眼部分的上方。钻井，定位，固定和隔离步骤可以在井眼部分不暴露于延伸到地面位置的液柱的同时进行。钻井，定位，固定和隔离步骤可以在钻柱的单次行程进入井眼中进行。
